They still exist in parts of the world but are disappearing in pace with introduction of modern methods which do not involve open exposure of the sludge. Here I report a five-year study from a Swedish plant with open sludge ponds in the 1950s when many similar ones were still active. I counted the waders with frequent visits from 18 April through 2 November, 1952–1956. Ninety-three percent of the dates had a visit in at least one of the years giving an almost complete combined coverage of migration. Nineteen species were recorded at least once. The total average annual number of bird-days was 2868 (5% in spring). Most abundant were the Ruff Calidris pugnax with 35% and Wood Sandpiper Tringa glareola with 32% of all bird days. Temminck’s Stint Calidris temminckii showed the highest spring proportion of bird-days, 30%.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41548268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Winter records of Blackcaps are not uncommon in Sweden but this is the first recovery of a bird with documented southern origin. The finding is in line with reports that a relatively high proportion of ringed Blackcaps is recovered in the same autumn north of the ringing site, and that the fraction of short-winged Blackcaps of presumed southern origin increases late in the season at Swedish bird observatories. Although the present record provides evidence that Blackcaps wintering in Sweden may originate from Continental Europe, it appears unlikely that the Blackcap will be able to evolve a new migration pattern, similar to the population of Continental Blackcaps wintering in Britain, because few Blackcaps seem to survive the Swedish winter.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46562281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most important breeding sites for waders were closely monitored in several years, 1969–1981 and again 2015–2018. Most species declined strongly, with the exception of Charadrius dubius which colonized exploited peat bogs without vegetation and open man-made gravel surfaces. Some mires were drained in the first study period, which can explain up to 20% of recorded population declines of some species (Pluvialis apricaria, Numenius arquata, Tringa glareola). Other likely causes are earlier hay harvest and with different methods. Abandonment of cattle grazing of pastures on many small farms also occurred between the study periods. Several wader species forage on wet pastures. Predation on small young of waders may have increased. The crane Grus grus has increased dramatically in the study area and small young of waders most likely is part of the food of cranes. Changes at foraging sites during migration and in winter may be contributing causes of wader declines as well as climate change.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42034811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such pale birds are known to appear with a low frequency throughout the species’ range. Superficially they look like the eastern (sub)species Parus (major) minor. The focal bird was a yearling with a wing length well above that of minor so there is no reason to suspect eastern origin. The yellow pigment, a carotenoid, is obtained through food, particularly green larvae. Such larvae were available in reasonably high numbers in 2006. The focal bird was an exception as no other pale Great Tit has been recorded during more than fifty years of fieldwork in the area. Yellow at the flange of the gape indicates that the bird had not completely lost its capacity to take up pig-ments, only the plumage was affected.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47551875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analyses are based on 1,512 successful breeding attempts of Common Buzzard, and 1,387 of Tawny Owl. The average number of young per successful breeding was 1.74 and 2.86, respectively. The variation between years was highly correlated between the two species, suggesting a common food source. In both species the between-year variation in clutch size was particularly large in beech forest territories, most likely caused by the effect of beech mast years on local rodent populations. The breeding density of Common Buzzard was particularly high in 1990–1995, coinciding with large areas of farmland set-aside. In the Common Buzzard, the yearly average number of young per clutch declined significantly with yearly average hatching date.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42569540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
